“It is rare for findings of fact to be varied. It should be emphasised that the process of reopening is only to be embarked upon where the application presents genuine new information. It is not a vehicle for litigants to cast doubt on findings that they do not like or a substitute for an appeal that should have been pursued at the time of the original decision. In Re E at [16] I noted that some applications will be no more than attempts to reargue lost causes or escape sound findings. The court will readily recognise applications that are said to be based on fresh evidence but are in reality old arguments dressed up in new ways, and it should deal with these applications swiftly and firmly.”
“The court will want to know… (c) whether there is any new evidence or information casting doubt upon the accuracy of the original finding.”
“42. The authorities identify two types of case where justice provides an exception to an estoppel preventing re-litigation of the same issue between the same parties: i) First, and obviously, an anterior judgment can be challenged on the grounds that it was fraudulently obtained: Takhar v. Gracefield Developments Limited[2019] UKSC 13 ,[2020] AC 450 . ii) Second, an anterior judgment can be challenged on the ground that new facts have emerged which strongly throw into doubt the correctness of the original decision. In Arnold v National Westminster Bank Plc[1991] 2 AC 93 at 109 Lord Keith of Kinkel stated: "….there may be an exception to issue estoppel in the special circumstance that there has become available to a party further material relevant to the correct determination of a point involved in the earlier proceedings, whether or not that point was specifically raised and decided, being material which could not by reasonable diligence have been adduced in those proceedings. One of the purposes of estoppel being to work justice between the parties, it is open to courts to recognise that in special circumstances inflexible application of it may have the opposite result …" This exception echoed the well-known decision of the House of Lords in Phosphate Sewage Company Limited v Molleson(1879) 4 App Cas 801 where Lord Cairns LC held that an anterior judgment can be challenged where additional facts had emerged which 'entirely changes the aspect of the case' and which 'could not with reasonable diligence have been ascertained before.' In Allsop at [26] the continuing validity of this exception was affirmed by the Court of Appeal. 43. It therefore seems to me that Jackson LJ's test of "there must be solid grounds for believing that the earlier findings require revisiting", ought to be interpreted conformably with these exceptions if a divergence from the general law is to be averted. This would mean that "solid grounds" would normally only be capable of being shown in special circumstances where new evidence had emerged which entirely changes the aspect of the case and which could not with reasonable diligence have been ascertained before. … 45. For my part looking at the matter from first principles I cannot see any reason why the general substantive law of res judicata should not apply to children's cases. … … 49. I naturally accept that Jackson LJ's test is binding on me. I completely agree that there should be a Stage 1 form of permission filter. I completely agree that on a rehearing application mere hope and speculation will never be enough to gain permission. I am merely suggesting an interpretative reconciliation between the solid grounds test and the general law such that solid grounds will normally only be demonstrated where either the fraud exception, or the special circumstances exception, is satisfied.”
